Campus Crime Neutralization Method Using Dual-Tone Multi-Frequency Enhanced 2-Way Radio

ABSTRACT

Disclosed is a Crime on Campus Neutralization System comprising a communication network of 2-way radios connecting a USER to a USER-REPEATER, subsequently to a LINK-REPEATER, enabling a USER to ultimately initiate a LOCK-DOWN procedure on a CAMPUS. Further disclosed, here within, are methods that enable the system to work effectively. This system is very cost effective, consisting of components that can be bought off the shelf. The system is unique in that it does not use the internet, a cell-phone device, a tablet, a computer, or any other device that, by its design, could be “hacked” or “compromised” by outside parties. The system is not complex, unlike other systems which rely on extensive software programs, but instead relies on a 6 decade proven technology.

Withoutusing of the internet, of a WI-FI device, a cellular phone, a tablet, acomputer, or a Graphic User Interface (GUI), the present inventionsolves this problem is a very cost effective manner, by assemblingvarious components in a unique fashion and by employing the system ofthese components in a unique process that can be installed andmaintained by and only a moderately skilled service person

Description of Prior Art

US application patent 2016/0006870 to Merjanian; Vic et al., describes acommunity safety and health communication and notification system. Thepatent application is restricted to a notification system throughout aspecific community that provides two-way communications between usersand administrators as to what they describe as direct police communityinteraction. This patent application is limited to a communicationsystem and uses such communication devices as a mobile phone, a laptop,a desktops, a tablets, a wearable communication devices such as aSmart-watch or a PDA. The present invention does not use any of thebefore mentioned technologies, which are often prone to being “hacked”or bing “compromised”. In addition, the Merjanian invention does not usea conventional 2-way radio based system.

US patent application 2015/0379861 to DeMaraa, II; Daniel Joseph,describes a system and method for automatic alert and lock down. Thesystem is launched by an authorized user entering an authorization codeon a device, which triggers an alert to law enforcement agencies andalso initiates certain lock-down procedures, including visual and audioalarms. Further, in the patent's abstract it described the invention asusing a “device each having an app installed therein for communicationwith the EMNS over a network”. In the present invention, the inventordoes not describe the use of any device using an app on a network,rather that the present invention uses a 2-way conventional 2-way radiosystem as its bacc-bone. Further, the devices of the current patentapplication, are of a conventional 2-way radio design, and not a tablet,a cell phone, a desktop computer, or any other device using a Web basednetwork.

US patent application 2015/0215755 to Bekanich, describes a school widelock down and emergency communications system, further describing agraphic user interface (GUI) with a wireless device based on a one-waymessage to law enforcement over a restricted law enforcement radiofrequency. The patent application further asserts in their claim 1 thatthe method shall comprise, “a computer-implemented method forcommunicating digital information comprising (the) sending an emergencymessage in a digital format from a location, the message directed to aleast one 911/emergency dispatcher or law enforcement individual . . .”. In the Bekanich applied for patent, it is obvious that the inventoruses different mode of emergency transmission by using the Web, bycellular system, or by WI-FI network, none of which are used by thepresent inventor concept. What is deficient in the current patent is thenotion that the use of the Internet is secure, and can not be “hacked”or “compromised”.

The patent application to Ergenbright 20150204109 described a method andsystem for mitigating the effects of an active shooter. The applicationfurther described a method comprising an aggressor mitigating sequencethat includes; automatically controlling ingress by one or more entrydoors of a building; automatically notifying response personnel of theaggressor event; providing command and control functionality to theresponse personnel; and automatically broadcasting predeterminedmessages via one or more communication media. The patent applicationappears to describe a one-way communication system which both notifiesresponding personnel and automatically initiates a lock-down procedure.The device appears not to be human operated, but rather it activates bya device that detect the sound of gunfire. In the present inventor'spatent application, the decision making is not done by an electronicdetection device, but rather by a 2-way radio carrying person. Further,the present invention permits said 2-way radio user to activate “activeshooter” counter measures by sending a predetermined code from a 2-wayradio. Therefore, the present invention differs from that of patent byErgenbright in that it is user initiated, not initiated by a detector.

US patent application 2015/0170486 by Penland, describes a securitysystem for identifying disturbances in a building. It further describescameras and monitors, positionally located to record and transmitaudio/visual information. The system describes two activation states—onefor non-emergencies and one for emergencies, which allow a user to enterID information to retrieve a weapon in a storage compartment. Whilebeing a Dad, and wanting my 10 year old to have the best protectionpossible at her school, I would not allow a teacher to have at his orher disposal a firearm. That sends the wrong message to our children.But instead, in the present invention, a campus crime perpetrator can beneutralized using the process described here within. The presentinventor's patent would put 2-way radios in the hands of all teachersand administrative personnel, the radio capable of initiating alock-down procedure.

US patent application 2014/0306802 to Hibbs, Jr. describes an instantalert network system. The patent application relates to using acommunications device such as a mobile phone to provide an instant alertor push button alert that is communicated via the Web to certaincontacts within a contact base. The alert can be coded for differentevents. This Hibbs, Jr. patent depends on the use of the Web, whereasthe present invention does not make use of said Web, nor does thepresent invention provide alerts only to “certain contacts within a database”. Furthermore, the current invention relies on 6 decades of proventechnology that works independent of an Web, cell phone, WI-FI, or othernetworked technology, of which is prone to being “hacked” or to being“compromised”. Further, the Hibbs, Jr. patent application does not beginto address any process or method to neutralize a crime perpetrator, butonly alerts persons to the happening of same, nor does it enable anycrime perpetrator neutralizing devices, nor does it connect any USERdirectly to to any 911 operator, nor does it directly interconnect auser to a first responder on responder's emergency radio.

U.S. Pat. No. 8,873,719 to Clawson, described an active assailantprotocol for emergency dispatch. This patent DOES have an impressivelist of prior art patents, patent applications, and other relevantpublications on the state of the art. However, the patent is limited toproviding emergency protocol interrogation instructions and informationfor guiding a dispatcher during an emergency call. This patent haslittle or no relevance to the present inventor's claims, in that is doesnot use a conventional 2-way radio based communications system, nor doesit use a auto-phone patch (a device for interconnecting a radio to aTelco phone line), nor does it doesn't permit users to talk amongthemselves during an emergency event, nor does it suggest methods toneutralize a crime perpetrator once her or she has gain access to acampus.

U.S. Pat. No. 8,588,733 to Ferguson, et al., described a wireless deviceemergency service connection and panic button with a crime and safetyinformation system. The patent further describes providing a conduit ofinformation from an alarm button on a communication device via awireless system to what appears to be either a computer or a cellularphone of a receiving party. In addition, location and timing informationis provided. In reading the present patent and am lead to believe thatsaid patent is a system in which a user may activate an alarm condition,triggering a server to determine what other users are closest to saidfirst user, the server meanwhile researching data on the location ofsaid first user, there after a network of users is established that canbest help said first user in his or her immediate event. While this is aworth goal, it must be said that it is not in the realm of the presentinventors patent ideas. First, it does not provide a means to call a 911dispatch operator directly from any user device, nor does it notinitiate a lock-down procedure to neutralize a campus crime perpetrator,nor does it provide interactive prompting messages to the user radioperson, to assist them in activating other system functions, nor does itcomprise a system that is not Web or cell phone based. Therefore, thispatent is not relevant to the present inventor's patent application.

U.S. Pat. No. 7,813,750 to Hobby, described an emergency radiocommunication system incorporating integral public safety radio“bridging” capabilities. This system uses a bridge (or patch) tocommunicate directly between pubic safely radio systems and other radiosystems, such as schools, hospital, and other facilities. In the Hobbyinvention, only a 911 operator may “patch” the communications from aschool, hospital, or other facility to that of the public safety radio.But in the present patent application, the inventor describes a methodwhereby any user radio in a system of a school, hospital, government, orbusiness complex is able to communicate from the USER's site, through aLINK-REPEATER, directly to a first responder. It should be apparent fromthe above description that no “bridge” or “patch” is being used in thecurrent inventors application, and therefore the Hobby patent is notrelevant to the current patent application.

U.S. Pat. No. 7,277,018 by Reyes, et al, described a computer enablednetworked facility emergency notification management and alarm system.The patent further describes enabled system for monitoring events andupon a user's input, triggers alarms, including the capability of awireless access device being able to initiate or be alerted to thetriggering of an event alarm. After reading this patent I am of theopinion that the core of the invention centers around a secure computernetwork, which sends and receives text messages or alerts from suchdevices as cell phones, laptops, or computers in the aiding of selectingthe appropriate protocol for dealing with an emergency. No where in saidpatent did I read any mention of voice communications between users,whether by cell phone, laptop, or computer. The system's intent is tohave a data based protocol of accessing mapping, accessing lists ofmedical equipment and materials, but does address the issue ofneutralizing a crime perpetrator on a campus. Further, I do not find anymention of any voice communications with a 911 emergency operator, norany radio-to-radio voice communications with first responders. I do notsee how this system can prevent, in any way, the killing of dozens ofvictims in the first 7-10 minutes of a mass shooting or a coordinatedattack by a group of individuals on a facility.

U.S. Pat. No. 5,903,216 to Sutsos et al., described a security structurefor unlocking the security for use by emergency response and authorizepersonnel. It described components and a method of using a scanner toscan the emergency response frequencies to first responders to unlock oropen a gate when a scanner recognizes first responder's radiotransmission on the restricted frequency. Of course the gate would alsorespond to recognized user's frequency and code like those provided in agarage door opener. The current invention has little or no relevant tothe the present inventor's process, in that it does not describe the useof a conventional 2-way radio system, nor does it use of a repeater insaid system, nor does it use of a LINK-REPEATER described by the presentinventor's application. Further, it does not include a feature thatallows a USER-RADIO's to automatically be connected to a 911 operatorupon the initiation of a LOCK-DOWN procedure, nor does it facilitate thedirect communication from a user to a first responder.

SUMMARY OF THE INVENTION

An INVENTION to neutralize a crime perpetrator on a campus, comprising aUSER communicating to a USER-REPEATER, further communicating, through aLINK-REPEATER, to affect the neutralization of a campus crimeperpetrator. Said neutralization shall be accomplished using acombination of containment, obstructive, and informational devices,including the use of a public address system, the lowering of acontainment chain-link barrier, the releasing of thousands of 30-50 mmplastic balls in hallways, corridors, and vestibules, a directinter-connection of a LINK-REPEATER to a first responder base station,and a automatic dialing to a 911 operator from a USER radio.

It is therefore a primary object of the present invention to provide aprocess whereby an individual USER holding a convention 2-way radio cantotally LOCK-DOWN a CAMPUS.

It is another objective of the present invention to offer a very costeffective system to the public which can affect the saving of hundred,maybe thousands, of innocent lives.

It is another objective of the present invention to offer a solution tothe current problem of a solution not involving vulnerabilities ofoutside persons “hacking” or “compromising” the integrity of the currentsystem, as is often time the case when using the Internet, or when usinga cell phones, or when using any other device that is connected to theInternet.

These and other objects of the present invention, will become apparentto those skilled in the art upon reading the accompanying description,drawings, and claims set forth herein. The headings provided herein arefor the convenience of the reader only. No heading should be constructedto limiting upon the content in any way.

3. How to Use the Invention

A school, a municipality, a government, or a business entity may usethis invention to greatly improve the level of said institution'sability to protect themselves against a campus crime perpetrator. In theevent that said perpetrator is recognized on campus, any personnel witha UNIQUE or NON-UNIQUE radios (FIGS. 1 and 2) can initiate a LOCK-DOWNprocedure using their conventional 2-way radio portable. Most schools atthis time are currently using 2-way radios to perform ancillary taskssuch as traffic control, contacting maintenance personnel, andcontacting teachers on a playground. Therefore, it is a logical furtherstep to incorporate this already accepted technology in an extendedapplication that can have a great impact in reducing the number ofkillings on various campuses. The cost of the invention is considerablylower than any other solution currently available. When a USER sees apotential crime perpetrator, he or she may activate a LOCK-DOWNprocedure by keying the UNIQUE or UN-UNIQUE radio and pressing apredetermined DTMF code on a UNIQUE radio, or perform a sequence ofinter-active responses to voice prompts on a UN-UNIQUE radio.

What is claimed is: 1) A Crime on Campus Neutralization System, fornotifying persons on a CAMPUS of an impending lethal threat, and furtherneutralizing said perpetrator before he or she can maim or kill dozensof persons, comprising: a plurality of USER REPEATERs, each consistingof 2, conventional 2-way mobile radios, a notch-only mobile radioduplexer, a micro-processor based repeater controller, a Mp3 audio filerecorder/player, a ancillary CTCSS (PL) decoder module, a conventional2-way mobile LINK-RADIO, a plurality of band specific transmit/receivegain antennas, a 12 volt DC power supply with deep cycle batteryback-up;
